Fred, you want to blind everybody? Stick with 80-100w bulbs, the wiring won't handle much more than that; if fact I've replaced several Combination(turn sig) switches on this model car w/std. bulbs. Don't worry about alternator output, 100w divided 13v=about 8amps. of current flow. Stock bulbs use about 5amps.
